NLC5.1ST User Manual
Rack Mount Installation
The NLC5.1ST chassis has four rack mounting holes and has been designed to fit in a standard 1RU
space. Plastic ‘finishing’ washers are recommended to protect the painted surface around the mounting
holes. Locate the air vents on each side of the unit, and be sure to keep them clear so the unit may
have adequate ventilation.
Power Connection
The AC power cable supplied with NLC5.1ST must be connected from the IEC320 power entry module
to an AC mains outlet with a functional earth ground connection. For protection against electric shock
and electro-magnetic interference, do not plug the power cable into a ground lifting adapter or remove
the cable’s grounding pin. If in doubt, please consult a qualified electrician.
NLC5.1ST is designed with reliability in mind and contains two auto-switching power supplies. Please
connect NLC5.1ST to an uninterruptible power supply (UPS) to protect against power surges and low-
voltage conditions. For maximum redundancy, connect each power supply to a separate UPS on
different power circuits. NLC5.1ST may be combined with other devices on the output of the UPS as
long as the total load is within the UPS’ capacity. Consult your UPS manual for details.
NLC5.1ST will automatically power up when AC power is applied. If AC line power is lost or
momentarily interrupted, NLC5.1ST will revert to its previous state when the power is restored. Hard-
bypass relays will pass through audio directly to the outputs when the unit is unpowered. However,
audio cannot be de-embedded from the HD/SDI input and bypassed to the AES outputs while the unit
is unpowered.
Front Panel Controls and Indicators
Bargraph Meters
INPUT LEVELS
– Eight 10-segment multi-colored LED meters display the true-peak audio level for
each channel of the audio stream. Bargraph meters will display either input or output levels, selectable
from the home screen.
Status Indicators
AES LOCK -
Green LED indicator illuminates when NLC5.1ST has acquired a valid AES3 or HD/SDI
digital input signal.
AES ERROR
- Red LED indicator illuminates when a valid signal cannot be found, or the signal is
received corrupted. Check input settings for proper configuration.
